DataGridView bind to DataSet which read data from a XML file, when I edit the cell value and save back, it's ok; but when change the cell value programmaticlly, the value can not save back to XML file. Help , please! > DataGridView bind to DataSet which read data from a XML file, when I > edit the cell value and save back, it's ok; but when change the cell > value programmaticlly, the value can not save back to XML file. Change the cell value programatically by doing what, exactly? (show some code). The value cannot save back to XML, how exactly? Is an exception being thrown? (show some code) -cd 1. dgTrack.Rows[Row].Cells["Picture"].Value = Picture; dgTrack.Rows[Row].Cells["Longitude"].Value = Longitude; dgTrack.Rows[Row].Cells["Latitude"].Value = Latitude; dgTrack.Rows[Row].Cells["Radius"].Value = Radius; dgTrack.Rows[Row].Cells["Audio1"].Value = objAudio.C1; dgTrack.Rows[Row].Cells["Audio2"].Value = objAudio.C2; dataSet.WriteXml("setting.xml"); No exception is thrown.

I think you may need to call DataSet.AcceptChanges before WriteXml to make the edited valus "stick". -cd Hi Daniel, I found that I can't write back XML everytime after I use OpenFileDialog to find a file, otherwise it's OK. Thanks! >> 1. dgTrack.Rows[Row].Cells["Picture"].Value = Picture; >> dgTrack.Rows[Row].Cells["Longitude"].Value = Longitude; [quoted text clipped - 10 lines] > > -cd Hi Carl, It's because OpenFileDialog changed the current directory.
